Abstract

The present invention relates to filter capsules for showers and sinks used in surgical settings, clean rooms and other contaminant-sensitive settings having modified outlets for improved splash control.An inlet that extends upwardly from a cap of the filter capsule has axis offset from the longitudinal axis of the capsule, wherein the capsule orientation permits directional control of the fluid path for fluids exiting the capsule/cartridge and rotation of the capsule about the inlet connection point rotates the fluid about a circular path.A filter capsule comprises: a capsule wall, a filter cartridge, a capsule top cap having an inlet with an axis offset from a filter capsule longitudinal axis, and a recessed outlet having a recessed outlet wall extending inwardly into a filter cartridge core.
